Sorry if I insist
I deleted all my seasons folder; installed the default from the CD with just the original tracks. I deleted iGOR.ini and let the program make a new one, then changed the racelist server.
The result is the same. I don't see how it can be something coming from my side

Well, I can live with that. It just felt weird; I never see something like this before and I don't have any season entry for that track now
